What makes dogs break out in hives and what do you do for them?

I have a Boxer puppy. No change in food. No changes in anything like soap or anything. Today, she just starting breaking out in hives. I dropped cookie dough on the floor earlier and she got to it before I did. Could it be the peanuts or peanut butter?

she could be allirgic to cookie dough and whats in it

Call the vet

Im not sure if it could have that effect. my advice to you would be to give your dog a lot of water to drink, to dilute that peanut butter. Then take him/her to the vet asap.

Im not sure about anything else that could have caused him to break out. I do have a friend who's dog is allergic the their carpet so all him hair fell out. Weird huh? maybe your dog is allergic to something, or is sick.

Tracey, I would take her to the vet ASAP. I never, in all my years owning a dog, have ever seen it break out in hives. it could be minor or it could be major. you never know. call your vet before heading over because, like I said, it could be minor.

Best Wishes to you and your puppy!

It could be an allergic reaction, keep an eye on it if your puppy continues to get hives check for fleas and change food/treats. Alot of dogs are allergic to chicken products. I vet could also help to determine the cause.

Allergies and you have to get them steroid shots cause they can die from allergies. Good luck and I hope I helped. but take to the vet and have them checked out . No one on here is a vet Im sure.
